If what you want is to buy local currencies the obvious answer is create an account in the bank of those nations so you can buy all the "inflation money" you want.

But i assume that you already tought about it and that is not an easy option for you, so the main problem with this local currencies is the control of the goberment over the exchange market, making really hard for a person in other countries to get them, and for people in those countries to exchange that money for other currencies.

I can give you an advice on Venezuelan Bolivar and it's that the Central Bank is going to make a "monetary reconversion" taking 3 ceros away from the currency.

So i don't recomend you to buy (at least physical Venezuelan Bolivars), untill they release the new bills.
